STS9’s tour brought them to the House of Blues in Boston on April 20 and the band got some help from legendary bassist and Bela Fleck & the Flecktones member Victor Wooten as he joined the band for “Grow” in the middle of the second set.

Wooten is on hand as an instructor at Berklee School of Music this summer running a bass workshop along with longtime collaborator Steve Bailey, Berklee’s Bass Department chair.

Watch a clip of Wooten with STS9 above.
